Hey. I'm just wondering, why does my N9 have these problems?

1. My videos appear in my music library. When it plays them, it just crashes. How do I fix it?
2. Every time I turn it on, it says "Connect to internet?" I don't know if it's just me or I hadn't experienced this somewhere...
3. Why does the music player read the filename of the .mp3 as the title? I had to rename it all manually, and it still persisted on some tracks.
4. How do you shrink the space allocated for apps? it says 4.2 GB is reserved, and I don't usually install that much apps.
5. Is there an app like Nimbuzz or any YouTube downloaders like in Symbian?
6. How do I disable the auto-rotation? It's annoying, while using swype in bed.
7. Is a screen protector recommended? it came without one and I was told not to since most of the gestures involve swiping from the edge. Does anyone use a screen protector?
8. Is there a place where I can string a lanyard? I usually do that with other phones...

Sorry for all the questions, I just got this last monday and it's an all new OS...
